Verus Engineering Air Oil Separator (AOS) for Subaru WRX/STI (VA)

The Verus Engineering Air Oil Separator (AOS) is a cutting-edge solution designed for the 2015-2021 Subaru WRX/STI (VA) models. This essential component ensures that your intake system remains oil-free, thereby preventing potential issues such as detonation, power reduction, and carbon build-up. By effectively filtering both the crankcase vent and intake filter locations, the AOS is a single-unit solution that maintains peak performance without altering your vehicle's tune or setup.

Superior Filtration and Durability

The Verus AOS is engineered with precision, featuring four 5-micron coalescent filters that effectively trap particulates larger than 5 microns. This advanced filtration system, combined with stainless mesh and internal baffling, provides unprecedented air filtration for the crankcase air. Additionally, the optional coolant hook-up kit allows for the circulation of hot coolant through the AOS, reducing condensation build-up during colder months. The anodized parts are corrosion-resistant, ensuring long-lasting durability even in the intense engine bay environment.

Included Components and Specifications

The Verus AOS comes with a comprehensive set of components, including the assembled AOS, four coalescent filters, internal baffling, stainless mesh, and a sheet steel bracket for the VA chassis (LHD only). The package also includes various rubber hoses and a hardware bag with all necessary parts for a seamless installation. The AOS is CNC machined from 6061-T6 aluminum, featuring Mil-Spec O-Ring Bosses for a secure fit. Each part is anodized for corrosion resistance and CNC laser engraved for durability. This product is proudly made in the U.S.A., reflecting Verus Engineering's commitment to quality and excellence. Experience the difference with the Verus Engineering Air Oil Separator (AOS) for your Subaru WRX/STI (VA) today!
